SU28199A1 - Printing method main dyes mi - Google Patents

Description

The proposed printing method of the main dyes is based on the use of a phenol sulfonation product as a fixative. The resinous substance released during the precipitation of this product with acids together with the main dye with the addition of alcohol and phenol is used for printing in order to keep the lacquer formed in solution. It is also possible to precipitate the fixative T with zinc acetate, and the release product in this case serves the same purpose as the above resinous substance.

The printing process itself is carried out as follows.

I. Per 100 kg of fixer T, 66 kg of 30% acetic acid are applied, the upper liquid layer is drained, and the released resin is repeatedly washed with water until the washed water becomes colorless and neutral. The resin yield is 40-45% of the weight of the initial fixer T. The first fluid that drains a significant amount of acids is used for the next operation of precipitating a fresh fixer, using in this case a smaller amount of acids for the same amount

source fixer. Resin obtained :; dissolves in alcohol and alkalis and has a large anchoring capacity. This preparation can be used to print the calico goods with basic dyes while simultaneously fixing them on the fabric, so that subsequent posting through the emetic solution becomes unnecessary. The ingredients of the mixture are taken in the following proportions:

dye base,

wood alcohol,

phenol,

resin fixer,

water.

traganta.

1,000 Z.

In bills, resin, phenol and alcohol must be added in the following proportions: 30 I alcohol,

25 g of resin fixer, 85 g of phenol, 860 g of tragantha.

1,000 2.

Or, 40 hours of phenol, 15 hours of wood will be taken in notes without a fixer.

 alcohol, 45 parts of water and 900 parts of traganta. .. For some dyes, such as rhodamine B, methylene blue B, for example, 40 g of resin should be taken, for others, such as methyl violet N, blue radins 5B, and 20 g is enough: moles. The amounts of pitch, phenol and alcohol in bills should also be changed, depending on the degree of the bill, phenol serves to keep the lacquer of the vehicle and fixer in solution and can be fully or partially replaced with resorcin. From the printing press, the product enters a brew or a steamer, is washed in a pass-through apparatus, is spirited and trimmed with a regular one.

Ii. Another substance fixing the basic dye is the product of the fixative T precipitating with an acetic acid powder, paste and fixing agent. A fixative and 30 kg of acetic zinc are obtained from the UOkg after repeated washing of a 65-c / paste paste, which includes the VB composition of the mixture of substances used for printing:

20 g dye basic, 60 g wood alcohol,

150 g of water

150 g of phenol,

120 g of pasta fixer,

500 g of tragantha.

1,000

They also bill with a fixer paste also phenol and wood alcohol. The wiring of the goods is the same as when applying the first method: parking (or brew), soap maker, spirit lamp and trim.

Pre, dmet patent.

The printing method of basic dyes using phenol as a fixative for sulphurization product, characterized in that a resinous product obtained by precipitating the sulphurization product of phenol with patent Patent No. 12094, with the addition of phenol and alcohol, is added to the dye to fix it. lacquer solution.
